Nodular regenerative hyperplasia of the liver in renal transplantation.

In our series of RT three cases of diffuse NRH of the liver were found. This rare entity is characterized by nodules of regenerative hepatocytes distributed throughout the liver without fibrosis. The incidence was 12.5% and probably is underestimated. Clinically, hepatomegaly, moderate thrombopenia and an elevation of GGT were present, but no case was previously suspected. NRH can lead to PH, and we should think of this entity in the differential diagnosis of PH following RT.
